Okay all, I need to have an object that isn't changeable after it has been created ( unmutable ). Hibernate apparently has an EJB3 extension called mutable ( see/
http://www.hibernate.org/hib_docs/annot ... pec-entity
)

and

http://www.hibernate.org/hib_docs/annot ... l#mutable()

... But I have no idea how to use it. Eclipse gives me nothing but error's, and I can't find an example of it anywhere. I've tried things like:

@Entity
@Mutable(value=false)

and

@Entity(mutable=false)

etc...

and nothing is accepted....( I know this can be done with mapping files, but I'm trying to figure out how to do it with Annotations )


Please help :-) ( email or msn me any time if you require more info )

cheers,



Operating System:
FreeBSD 5.4

Hibernate version:
3.1alpha1

Name and version of the database you are using:
MySQL 4.1.12

Java Version:
1.5.0-p1

The following appears to work! :-D ( compiles nicely - I'll perform additional tests to confirm - absence of additional post = good result :-D. More posts here by me means :-( )

--------------------------------------

package com.sas.heartbeatmonitor.businessobjects;

import java.util.*;
import javax.persistence.*;

@Entity
@org.hibernate.annotations.Entity(mutable=false)
public class HeartBeatUpdate {...

Year, packaging is the confusing thing, I need to make the doc more clear.
